Notes
FOR A CHOCOLATE GARNISH:
Before you add any ingredients, hold the glass at a 45° angle and drizzle in a thin stream of the syrup, turning the glass back and forth a couple of times as your swirl.
Add ice to a shaker, followed by the cocktail ingredients. Then, seal the shaker and shake well.
Fill the glass with ice and pour the cocktail over the ice.
